Auto Memory Keeper

Overview

Automatically extract session content and update daily memory files to maintain long-term memory continuity.

Two modes:

• Passive mode: Cron job runs hourly (automatic)
• Active mode: Manual trigger by user ("remember this", "log today")

How It Works

Triggers

1. Auto-trigger: Cron job runs every hour
2. Manual trigger: User says "remember this", "log today", "update memory"

Workflow

Step 1: Check Environment

DATE=$(date +%Y-%m-%d)
MEMORY_FILE=~/.openclaw/workspace/memory/${DATE}.md

if [ ! -f "$MEMORY_FILE" ]; then
  echo "# ${DATE} Log\
\
## Today's Items\
\
- " > "$MEMORY_FILE"
fi

Step 2: Fetch Recent Sessions

# Use sessions_list to get active sessions in last 60 minutes
# Use sessions_history to get session details

Step 3: Noise Filtering

Skip these message types:

• Simple greetings ("hi", "hello", "hey")
• Acknowledgments ("thanks", "ok", "sure", "yes")
• Single word responses
• Questions without context
• HEARTBEAT_OK messages
• System messages

Step 4: Extract Key Info

From filtered messages, extract:

Step 5: Smart Deduplication

Check for duplicates before recording:

# Read current file content
# If similar content exists (>80% similarity), skip
# Otherwise append

Step 6: Update Memory File

Format:

## Today's Items

- {time} {item description}
- {time} {item description}
...

Examples

Input (user message):

"installed openclaw-tavily-search, score 3.639"

Stored:

- 21:47 installed openclaw-tavily-search skill (score 3.639)

Input (user message):

"auto-extract session content to memory file every hour"

Stored:

- 21:50 created auto-memory-keeper skill for hourly auto memory extraction

Configuration

Configurable via config.json:

{
  "memory_dir": "~/.openclaw/workspace/memory",
  "interval_hours": 1,
  "active_minutes": 60,
  "categories": ["Decision", "Task", "Progress", "Issue", "Conclusion"],
  "skip_patterns": ["^hi", "^hello", "^thanks", "^ok"],
  "dedup_threshold": 0.8
}

Quality Rules

1. Concise - One sentence per item
2. Timestamp - Always include time
3. Dedupe - Avoid duplicate entries
4. Categorize - Classify by type
5. Skip noise - Don't record trivial messages

FAQ

Q: How to trigger manually? A: Say "remember this", "log today", or "update memory"

Q: Where is cron configured? A: Use cron job add command, see example in SKILL.md

Q: Where are memory files stored? A: ~/.openclaw/workspace/memory/YYYY-MM-DD.md

Testing

Periodically review memory files and adjust skip_patterns for better filtering.
